Mastertrack UN All Steel 1 is a radial ST all-season tire that was designed for trailers with long-haul applications. The tire features radial design that lets the tire cool down and have a longer life. Its four wide circumferential grooves assist with getting the water and slush away from the tire's footprint, which avoids hydroplaning and increases stability on the road. Symmetric tread design on this trailer tire prevents irregular wear formations across the tread area, while its lateral grooves help with additional water and slush removal.
